mediaforum.net
Professional communities in media are fragmented across social platforms and private groups, and a dedicated space would find an audience. Journalists, broadcasters, publishers and the technology people serving them have nowhere neutral to talk.
Media forum covers that reading and the event one. Media forums are run by industry associations, press freedom organisations and broadcasters, usually as senior-level gatherings about the state of the industry, and owning the category phrase is a strong position for a recurring event.
The .net suits both, reading as a network, which is what a forum is, with an audience that never types a guessed address.
Two common words, no hyphen, twelve characters, standard in every market with a media industry.
Offers considered.
